i vention,a removable anvil 2 is inounted in a setting asaw, howeve r,has continued to be 15 v t a 1 cause the set thusproducedis the mostperi deslred to usethesaW set so as tohold it the base member 4: Qf thQstructurafwhich I has pointed projections 6 'thatmay be driv- -eo eninto the benoh orother place where it is shaped or crosswise and stillthe groove, the side edges ;,of the anvil being slightly concave so thatthey cooperate with a lockingball 10 springpressed into the groove 8 onthat side of the groove remote from the tooth-posio a The anvil 2. isprovided with four setting supporting face l6 of the,anvil ofset-limitedges 1 beingin such relation to the gage 12 ineach position ofthe anvil thatwhen 30 the pointof the saw tooth to be set abuts againstthe gage 12 the setting edge lt will be at ithe desiredpoint of bend ofthe tooth to be set and .thefaeedS on the gage side of the setting edgewill limit the amountof "set 85 ated and operated w f h thgwhen theanvil 2 i in position 111 the groove 8 of the base 4,theblade-supporting surface 16 of the anvil will preferably be in sameplane as the upper faceZO of the base 4 which thus forms an extension ofthe blade-supporting surface of the anvil. Moreover, the base 4 willpreferably be of such thickness from top to bottom that when 6. thepointed studs or projections 6 are driven ting member 22 having atooth-engaging face 24 which lies substantially parallel to theset-limiting face '1 8 of the anvil 2 when i it has operated to bend thesaw tooth into set condition, said setting member being preferablyprovided with an impact-receiving face 26 on its side oppositethe'toothengaging face 24 so that when struck a hammer blow on the face26 the member 22 will transmit the impact to the saw tooth projecingover the setting edge 14 and bend,

this toothdown against the set-limiting face 18, the settingoperationthus being substantially equivalent to a hammer blow delivereddirectly upon the tooth to be set.

In order to support the setting member 22' and to guide it in itssetting movements, in the illustrativeembodiment of the invention thesetting member 22 is pivoted to rock about a shaft 28 carried betweenears 30 formed on the base l upon each side of a slot 32 extendingthrough the gage 12, in which slot and between which ears the settingmember 22 moves and is guided in effecting its saw-setting movements.

It will be noted that the tooth-engaging face, 24: of the setting member22 is inclined to the blade-supporting face 16 (if the anvil aswellas'to the blade-supporting face of the base 4 at an angleapproximating the desired angle. of set so that it will present asubstantial bearing surface upon the tooth when performing I the settingoperation and will thus cooperate more effectively with each of'theset-limiting faces 18; Preferably this angle of inclination isat leastequal to the greatest angle of inclination of any of the set-limitingfaces 18 to theblade-supporting face'16, c j j It will be noted from aninspection of Fig; 3 that the setting member. 22 projects suflicientlyover the anvil 2 so that its toothengaging'face 24 projects beyond thesetting edge 14 of the anvil a substantial distance.

The purpose of this isto avoid the necessity for using a spring or othermeans for moving the setting member away from the anvil when inserting asaw tooth beneath the setting member, it being merely necessary to restdirectly upon the tooth formed on said anvil, a'recess in said,

' being shaped and operative setting [2. Asaw set insert the point ofthe'tooth between the blade-supporting face 16 of the anvil and thetooth-engaging face 24 of the setting member. Thus, regardless of thethickness of the saw blade, the setting member 22 will to be set beforethe hammer blow is struck, which insures the uniform transmission of thehammer blow and a uniform set to successive teeth.

It will be understood that the invention is not-restricted to theillustrative embodiment but that many modifications may be made withoutdeparting from the fundamental concept, the scope of which is defined inthe claims.

What is claimed as new isi (1. Asaw set comprising a base having ablade-supporting face, a reversible anvil mountedin a recess in saidbase and having blade-supporting. faces on its, opposite sides eachhaving two intersections with said respective blade-sup porting faces ofinclined set-limiting faces i base in'which said anvil is mounted, saidrecess positioned to locate and maintain either blade-supporting face ofthe anvil in substantially the same plane as the V blade-supportingfaces: of the base, a gauge recess for engaging the toothed edge of asawto locatethe samewithrelation to the edge and set-limiting face ofthe anvil, and a setting member pivoted on said base and having a toothengaging face for engaging a sawtooth pro ecting over the operativesetting edge of the anvil and bending'said tooth into set condition,

said setting member having its tooth-enlgaging face arranged'to'contactwith the anvil when no sawv is in the set and extendingbeyond the setting edge to form, with the blade-supporting face of,theanvil, an angular entrance for the insertion of a saw setting edgesformed by the 7 tooth between the anvil and 'the setting member. 7 V V 7comprising a base having a blade-supporting face, a reversible anvilmounted in a recess in said base and having blade-supporting faces onits opposite sides" each' having two setting edges formed by the"intersections with 'saidjrespective bladesupporting' faces of inclinedset-limiting faces formed on said anvil, a recess in said base in whichsaid anvil is mounted, said recess being shaped and positioned to locateand maintain either blade-supporting face of the anvil in substantiallythe same plane as the blade-supporting faces of the base, a gauge formedbv the extension of one face I ofthe recess forengaging the toothed edgeof'a saw to locate the same with relation to the operative setting edgeand set-limiting face for engaging a. saw tooth rejecting over theoperative setting edge the anvil and bendingsaid tooth into setcondition, said setting member havingits tooth-enga ing face arranged tocontact with the anvll when no saw is in the set andextending beh yondthe setting edge to form, with the blade-supporting face ofthe anvil,an'angu lar entrance for the insertionof a, sawtooth 1 between the anviland the setting member,
